The reactions of isatin. benzotriazole. and succinimide with formaldehyde and methylamine yield monoamines RCH2N(Me)CH2R and methylenediamines RCH2N(Me)CH2N(Me)CH2R. The use of ethylenediamine as the amino component affords N,N'-disubstituted imidazolidines, while the reactions with 3-aminopropan-1-ol give N-substituted tetrahydro-1,3-oxazines. RCH2NBu21 was obtained from succinimide. formaldehyde, and diisobutylamine. Nitrosative cleavage of the amines obtained was studied: it was shown that monoamines and methylenediamines give N-nitrosoamines RCH2N(NO)Me, which were structurally characterized by X-ray diffraction analysis, RCH2NBu21 affords diisobutylnitrosamine. while imidazolidines transform into dinitroso compounds RCH2N(NO)CH2CH2N(NO)CH2R.
